• 2010 April Fools Joke

  - by Dane Morgridge

  I started at my current job at the end of March last year and there were some pretty funny April fools jokes.  Nothing super crazy, but pretty funny.  One guy came in and there was a tree in his cube.  We (me and the rest of my team) were planning for a couple of weeks on what we could do that would be just awesome.  We had a lot of really good ideas but nothing was spectacular.  Then Steve Andrews had a brilliant idea (yes it's true).  Since we have internal DNS servers we could redirect DNS to our internal servers for a site such as cnn.com.  Then we would lift the code from the site and create our own home page that would contain news about people in the company.  Steve was actually laughing so hard when he thought of the idea that it took him almost 30 minutes to spit it out. I thought, "this is perfect". I had enlisted a couple of people to help come up with the stories and at the same time we were trying to figure out how to get everybody to the site the morning of the 1st.  Then it hit me.  We could have the main article be one of my getting picked up by the FBI on hacking charges.  Then Chris (my boss) could send an email out telling everyone that I would not be there today and direct them to the site.  That would for sure get everyone to go to cnn.com first thing and see our prank.  I begun the process of looking for photos I could crop myself into and found the perfect one.  Then my wife took a good pic with our Canon 40D and I went to work.  The night before I didn't have any other stories due to everyone being really busy at work, but I decided to go ahead with just the FBI bust on it's own.  I got everything working and tested and coordinated with Chris for me to come in late so no one would see me at the office until after everyone had seen the joke. And so the morning of April fools came and I was waiting at home and the email was perfect.  Chris told everyone that I wouldn't be in and that not to answer any questions if you got any calls from anybody.  The Photoshop job I did was not perfect, but good enough and I even wrote an article with it that went into more detail about how I had been classified as a terrorist and all kinds of stuff. People at work started getting the emails and a few people didn't realize it was a joke (as I had hoped), including some from senior management (one person in particular who shall remain nameless in this post).  Emails started flying around about how to contain the situation and how to handle bad PR.  He basically bought it hook, line and sinker and then went in to crisis mode.  It was awesome! He did finally realize it was a joke and I will likely print and frame the email he sent out.  In short, April fools this year was a huge success.

• Write TSQL, win a Kindle.

  - by Fatherjack

  So recently Red Gate launched sqlmonitormetrics.red-gate.com and showed the world how to embed your own scripts harmoniously in a third party tool to get the details that you want about your SQL Server performance. The site has a way to submit your own metrics and take a copy of the ones that other people have submitted to build a library of code to keep track of key metrics of your servers performance. There have been several submissions already but they have now launched a competition to provide an incentive for you to get creative and show us what you can do with a bit of TSQL and the SQL Monitor framework*. What’s it worth? Well, if you are one of the 3 winners then you get to choose either a Kindle Fire or $199. How do you win? Simply write the T-SQL for a SQL Monitor custom metric and the relevant description and introduction for it and submit it via  sqlmonitormetrics.red-gate.com before 14th Sept 2012 and then sit back and wait while the judges review your code and your aims in writing the metric. Who are the judges and how will they judge the metrics? There are two judges for this competition, Steve Jones (Microsoft SQL Server MVP, co-founder of SQLServerCentral.com, author, blogger etc) and Jonathan Allen (um, yeah, Steve has done all the good stuff, I’m here by good fortune). We will be looking to rate the metrics on each of 3 criteria: how the metric can help with performance tuning SQL Server. how having the metric running enables DBA’s to meet best practice. how interesting /original the idea for the metric is. Our combined decision will be final etc etc **  What happens to my metric? Any metrics submitted to the competition will be automatically entered into the site library and become available for sharing once the competition is over. You’ll get full credit for metrics you submit regardless of the competition results. You can enter as many metrics as you like. How long does it take? Honestly? Once you have the T-SQL sorted then so long as you can type your name and your email address you are done : http://sqlmonitormetrics.red-gate.com/share-a-metric/ What can I monitor? If you really really want a Kindle or $199 (and let’s face it, who doesn’t? ) and are momentarily stuck for inspiration, take a look at these example custom metrics that have been written by Stuart Ainsworth, Fabiano Amorim, TJay Belt, Louis Davidson, Grant Fritchey, Brad McGehee and me  to start the library off. There are some great pieces of TSQL in those metrics gathering important stats about how SQL Server is performing.   * – framework may not be the best word here but I was under pressure and couldnt think of a better one. If you prefer try ‘engine’, or ‘application’? I don’t know, pick something that makes sense to you. ** – for the full (legal) version of the rules check the details on sqlmonitormetrics.red-gate.com or send us an email if you want any point clarified. Disclaimer – Jonathan is a Friend of Red Gate and as such, whenever they are discussed, will have a generally positive disposition towards Red Gate tools. Other tools are often available and you should always try others before you come back and buy the Red Gate ones. All code in this blog is provided “as is” and no guarantee, warranty or accuracy is applicable or inferred, run the code on a test server and be sure to understand it before you run it on a server that means a lot to you or your manager.

• Partner outreach on the Oracle Fusion Applications user experience begins

  - by mvaughan

  by Misha Vaughan, Architect, Applications User Experience I have been asked the question repeatedly since about December of last year: “What is the Applications User Experience group doing about partner outreach?”  My answer, at the time, was: “We are thinking about it.”  My colleagues and I were really thinking about the content or tools that the Applications UX group should be developing. What would be valuable to our partners? What will actually help grow their applications business, and fits within the applications user experience charter?In the video above, you’ll hear Jeremy Ashley, vice president of the Applications User Experience team, talk about two fundamental initiatives that our group is working on now that speaks straight to partners.  Special thanks to Joel Borellis, Kelley Greenly, and Steve Hoodmaker for helping to make this video happen so flawlessly. Steve was responsible for pulling together a day of Oracle Fusion Applications-oriented content, including David Bowin, Director, Fusion Applications Strategy, on some of the basic benefits of Oracle Fusion Applications.  Joel Borellis, Group Vice President, Partner Enablement, and David Bowin in the Oracle Studios.Nigel King, Vice President Applications Functional Architecture, was also on the list, talking about co-existence opportunities with Oracle Fusion Applications.Me and Nigel King, just before his interview with Joel. Fusion Applications User Experience 101: Basic education  Oracle has invested an enormous amount of intellectual and developmental effort in the Oracle Fusion Applications user experience. Find out more about that at the Oracle Partner Network Fusion Learning Center (Oracle ID required). What you’ll learn will help you uncover how, exactly, Oracle made Fusion General Ledger “sexy,” and that’s a direct quote from Oracle Ace Director Debra Lilley, of Fujitsu. In addition, select Applications User Experience staff members, as well as our own Fusion User Experience Advocates,  can provide a briefing to our partners on Oracle’s investment in the Oracle Fusion Applications user experience. Looking forward: Taking the best of the Fusion Applications UX to your customersBeyond a basic orientation to one of the key differentiators for Oracle Fusion Applications, we are also working on partner-oriented training.A question we are often getting right now is: “How do I help customers build applications that look like Fusion?” We also hear: “How do I help customers build applications that take advantage of the next-generation design work done in Fusion?”Our answer to this is training and a tool – our user experience design patterns – these are a set of user experience best-practices. Design patterns are re-usable, usability-tested, user experience components that make creating Fusion Applications-like experiences straightforward.  It means partners can leverage Oracle’s investment, but also gain an advantage by not wasting time solving a problem we’ve already solved. Their developers can focus on helping customers tackle the harder development challenges. Ultan O’Broin, an Apps UX team member,  and I are working with Kevin Li and Chris Venezia of the Oracle Platform Technology Services team, as well as Grant Ronald in Oracle ADF, to bring you some of the best “how-to” UX training, customized for your local area. Our first workshop will be in EMEA. Stay tuned for an assessment and feedback from the event.

• which metric(s) show the difference between object-oriented and procedural code

  - by twieger

  Which metric(s) could help to indicate that i have procedural code instead of object-oriented code? I would like to have a set of simple metrics, which indicate with a high probability, that the analyzed code contains procedural transaction scripts and an anemic domain model instead of following sound object-oriented design principles. Would be happy about any set of useful metrics and tools for measuring. Thanks, Thomas!

• Vimeo videos in iPhone app

  - by thomasvsundert

  Hi guys, I was wondering if there's a way to "embed" a Vimeo video in an iPhone app. For YouTube videos I'm using a webview containing the correct embed code for the YouTube video and the iPhone's native YouTube support will then transform the flash player into a YouTube button. Is there a similar way to play Vimeo videos from my app? Maybe someone knows the correct <video>-src for Vimeo videos? thanks, Thomas

• Need some guidelines on iPad animation programming

  - by thomasvsundert

  Hi, I'm creating an interactive e-book for the iPad. This book will contain multiple pages that will consist of a lot of animations (frame and motion animations), transitions,... I was wondering what my development options are, should I use OpenGL, Quartz,...? I've use UIImageView.animationImages before and found that it had really bad performance. What's the best way to draw frame based animations? Does anybody have some good pointers to resources on this? thanks in advance, Thomas

• Loading from pickled data causes database error with new saves

  - by hibbie

  In order to save time moving data I pickled some models and dumped them to file. I then reloaded them into another database using the same exact model. The save worked fine and the objects kept their old id which is what I wanted. However, when saving new objects I run into nextval errors. Not being very adept with postgres, I'm not sure how to fix this so I can keep old records with their existing ID while being able to continue adding new data. Thanks, Thomas

• iptables DNS resolution

  I have a virtual machine with Fedora 19 acting as a router. This machine as an interface (p8p1) with the IP 172.16.1.254 that is connected to another machine (IP 172.16.1.1) that's simulating the external network. I've installed snort 2.9.2.2, applied the snortsam-2.9.2.2.diff.gz patch and installed snortsam 2.70 on the routermachine In snort.conf besides altering some RULE_PATH I believe I've only added the following line to the file. output alert_fwsam: 127.0.0.1:898/password After doing this two comands: ifconfig p8p1 promisc /usr/local/snort/bin/snort -v -i p8p1 If I ping from the external network to the router IP, I can see the info about the pings.

• What algorithms are suitable for this simple machine learning problem?

  - by user213060

  I have a what I think is a simple machine learning question. Here is the basic problem: I am repeatedly given a new object and a list of descriptions about the object. For example: new_object: 'bob' new_object_descriptions: ['tall','old','funny']. I then have to use some kind of machine learning to find previously handled objects that had similar descriptions, for example, past_similar_objects: ['frank','steve','joe']. Next, I have an algorithm that can directly measure whether these objects are indeed similar to bob, for example, correct_objects: ['steve','joe']. The classifier is then given this feedback training of successful matches. Then this loop repeats with a new object. a Here's the pseudo-code: Classifier=new_classifier() while True: new_object,new_object_descriptions = get_new_object_and_descriptions() past_similar_objects = Classifier.classify(new_object,new_object_descriptions) correct_objects = calc_successful_matches(new_object,past_similar_objects) Classifier.train_successful_matches(object,correct_objects) But, there are some stipulations that may limit what classifier can be used: There will be millions of objects put into this classifier so classification and training needs to scale well to millions of object types and still be fast. I believe this disqualifies something like a spam classifier that is optimal for just two types: spam or not spam. (Update: I could probably narrow this to thousands of objects instead of millions, if that is a problem.) Again, I prefer speed when millions of objects are being classified, over accuracy. What are decent, fast machine learning algorithms for this purpose?

• Which LINQ expression is faster

  - by Vlad Bezden

  Hi All In following code public class Person { public string Name { get; set; } public uint Age { get; set; } public Person(string name, uint age) { Name = name; Age = age; } } void Main() { var data = new List<Person>{ new Person("Bill Gates", 55), new Person("Steve Ballmer", 54), new Person("Steve Jobs", 55), new Person("Scott Gu", 35)}; // 1st approach data.Where (x => x.Age > 40).ToList().ForEach(x => x.Age++); // 2nd approach data.ForEach(x => { if (x.Age > 40) x.Age++; }); data.ForEach(x => Console.WriteLine(x)); } in my understanding 2nd approach should be faster since it iterates through each item once and first approach is running 2 times: Where clause ForEach on subset of items from where clause. However internally it might be that compiler translates 1st approach to the 2nd approach anyway and they will have the same performance. Any suggestions or ideas? I could do profiling like suggested, but I want to understand what is going on compiler level if those to lines of code are the same to the compiler, or compiler will treat it literally. Thanks in advance for your help.

• Objective-C: Getting the True Class of Classes in Class Clusters

  - by TechZen

  Recently while trying to answer a questions here, I ran some test code to see how Xcode/gdb reported the class of instances in class clusters. (see below) In the past, I've expected to see something like: PrivateClusterClass:PublicSuperClass:NSObject Such as this (which still returns as expected): NSPathStore2:NSString:NSObject ... for a string created with +[NSString pathWithComponents:]. However, with NSSet and subclass the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { NSSet *s=[NSSet setWithObject:@"setWithObject"]; NSMutableSet *m=[NSMutableSet setWithCapacity:1]; [m addObject:@"Added String"]; NSMutableSet *n = [[NSMutableSet alloc] initWithCapacity:1]; [self showSuperClasses:s]; [self showSuperClasses:m]; [self showSuperClasses:n]; [self showSuperClasses:@"Steve"]; } - (void) showSuperClasses:(id) anObject{ Class cl = [anObject class]; NSString *classDescription = [cl description]; while ([cl superclass]) { cl = [cl superclass]; classDescription = [classDescription stringByAppendingFormat:@":%@", [cl description]]; } NSLog(@"%@ classes=%@",[anObject class], classDescription); } ... outputs: // NSSet *s NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *m NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *n NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject // NSString @"Steve" NSCFString classes=NSCFString:NSMutableString:NSString:NSObject The debugger shows the same class for all Set instances. I know that in the past the Set class cluster did not return like this. What has changed? (I suspect it is a change in the bridge from Core Foundation.) What class cluster report just a generic class e.g. NSCFSet and which report an actual subclass e.g. NSPathStore2? Most importantly, when debugging how do you determine the actual class of a NSSet cluster instance?

• Unable to build Python modules in Mandriva 2010

  - by SteveJ

  I am trying to build a Python module (pyfits) but I get the following error: # python setup.py install /home/steve/src/pyfits-2.2.2/stsci_distutils_hack.py:239: DeprecationWarning: os.popen3 is deprecated. Use the subprocess module. (sin, sout, serr) = os.popen3(cmd) running install error: invalid Python installation: unable to open /usr/lib64/python2.6/config/Makefile (No such file or directory) I get the same error when I try and build other modules so my guess is I am missing a Python development library. I am running Mandriva 2010.0, any suggestions?

• Flash crashing Mac?

  - by Bohdan Trotsenko

  In his recent blogpost, Thoughts on Flash, Steve Jobs says: We also know first hand that Flash is the number one reason Macs crash. My best guess is that Flash runs in user-mode, with restricted privileges. Is is impossible to crash a system having restricted privileges. What am I missing?

• Power scheme faulty [closed]

  - by user40287

  Hi, I use a laptop. When I take the power cable out to run on batteries, the screen darkens, as it is no longer so bright, to save on battery power. When I put the power cable back in, the screen brightens back to it's original brightness. However, I have since replaced the power cable, and the screen remains darkened. How do I regain the original brightness? Thanks, Steve

• Why won't my logon scripts map drives under Windows 7?

  - by Steven

  Why won't my logon scripts map drives under Windows 7? I'm using a vb script similar to the one below, the script runs using a group policy. Dim WshNetwork Set WshNetwork = WScript.CreateObject("WScript.Network") WshNetwork.MapNetworkDrive "g:", "\\\Saturn\data\" WshNetwork.MapNetworkDrive "k:", "\\\Saturn\stuff\" Works fine for Windows XP. Update: Copying the script locally and running it runs fine so I suspect the Group Policy isn't running the script on Windows 7. Many thanks Steve
